Which statements about a neutral atom are correct? Select all that apply. (1) A neutral atom is composed of positively and negatively charged particles. (2) The positively charged particles in the nucleus are positrons. (3) The electrons are attracted to the positively charged nucleus. (4) Positively charged protons are located in the tiny, massive nucleus. (5) The radius of the electron cloud is twice as large as the radius of the nucleus. (6) The negatively charged electrons are spread out in a "cloud" around the nucleus.

When an atom has equal numbers of electrons and protons, the electric charge of that atom is zero, so it is said to be a neutral atom.

Statement 2 states that the positively charged particles in the nucleus are positrons. However, this statement is incorrect as the positively charged particles are protons.

Statement 5 states that the radius of the electron cloud is twice as large as the radius of the nucleus. This statement is incorrect as the electron cloud’s radius is abouttimes of the nucleus’ radius.

Statement 1 states that a neutral atom consists of positive and negative charged particles. This statement is correct as both the protons and electrons are there in the neutral atom.

Statement 3 states that the electrons are attracted to the positively charged nucleus. This statement is correct as the electrons are negatively charged; they get attracted to the positively charged particles due to the law of attraction.

Statement 4 states that the positively charged protons are located in the tiny, massive nucleus. This statement is correct as the protons and the electrons are inside the nucleus.

Statement 6 states that the negatively charged electrons are spread out in a “cloud” around the nucleus. The statement is correct as the electrons and the protons makes a cloud around the nucleus.

Thus, the statement 1, 3, 4 and 6 are correct.
